/* ERROR/WARNING messages:

E: Illegal ... command

Self-explanatory.  Check the input script syntax and compare to the
documentation for the command.  You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.

E: Cannot use region INF or EDGE when box does not exist

Regions that extend to the box boundaries can only be used after the
create_box command has been used.

E: Variable evaluation in region gave bad value

Variable returned a radius < 0.0.

E: Variable name for region cylinder does not exist

Self-explanatory.

E: Variable for region cylinder is invalid style

Only equal-style varaibles are allowed.
